The product performance of FRP gratings used in sewage treatment plants is provided by the raw materials used for its production, among which unsaturated polyester resin is the main raw material that makes the grating plate have excellent corrosion resistance. As the base material of the grating plate, resin has the advantages of room temperature curing and molding, and the process performance is very flexible, which is particularly suitable for the production of FRP grating products.

In the sewage treatment system, a large number of guardrails, gratings, water treatment pools, etc. are used. In traditional projects, guardrails and gratings are mostly made of metal materials, such as welded steel pipes coated with anti-rust paint, which have strong corrosion-resistant wastewater treatment functions. However, the splashed water droplets and water volatilize very seriously to the metal. Over time, the metal corrodes and even damages, and there are many safety problems.

Sewage treatment plants have complex water quality, and some water has high pH value and strong corrosion effect. This requires that the raw materials such as grating pools, walkway boards, guardrails, etc. of sewage treatment plants have anti-corrosion effects. General iron materials obviously cannot meet the needs of use, stainless steel has high cost, and service life also has disadvantages.

Many FRP gratings in sewage treatment plants are 38*38 in size. Most FRP gratings have a load-bearing capacity of up to 4 tons per square meter. Therefore, don't be afraid that the FRP grating will be crushed. In addition, FRP gratings are corrosion-resistant and have little effect on them regardless of the usage. As a new type of composite material, FRP gratings are particularly suitable for sewage treatment and corrosive environments. The use of FRP materials in sewage treatment is also an inevitable trend. Not only FRP grating plates, but sewage treatment plants can also use FRP guardrails, FRP walkways and other equipment, which have a series of advantages such as long service life, low cost, safety and reliability, maintenance-free, and beautiful appearance.

Most FRP gratings in sewage treatment plants are made of FRP. The emergence of FRP materials has solved the anti-corrosion problem of products well, and can be used for a long time in harsh environments such as acid and alkali corrosion. It is a good substitute for traditional metal materials. FRP operating platforms are required in many occasions, especially in some corrosive places or working environments.
